7 years later, this monitor is long since discontinued but still the last monitor apple has made. They sell mac minis and mac pros with no matching displays at all, only 3rd party displays and adapters. And those mac minis I mentioned are a 4 year old model, and the mac pro is a 5 year old model.

The luscious backside of the Thunderbolt Display contains only a small line of specified ports:

Three powered USB 2.0 ports

FireWire 800 port

Thunderbolt port

Gigabit Ethernet port.

The Thunderbolt Display also comes with a built-in Thunderbolt cable attached to a Universal MagSafe cable.

It seems to be a convenient setup for connecting to your laptop's Thunderbolt port while charging. If you are sporting a Mid 2011 MacBook Air and your MagSafe port is opposite your Thunderbolt, you'll be glad to know the cable is long enough to reach.

There are three ribbon cables to disconnect before you can lift the display up to access the screw for the ground wire. The middle picture is misleading, at least on my monitor--you could only tilt up the display panel a couple of inches before you put strain on the ribbon cables. (Not a fan of this writing style at the expense of useful detail)

The 27-inch (diagonal) TFT active-matrix LCD has a resolution of 2560 by 1440 pixels, the standard for displays of this size and price. Its 12 ms response time and 16.7 million colors, however, fall short of the 6 ms response time and 1.07 billion colors of Dell's comparable display.

We might be splitting hairs here, but those hairs would be viewed with 1,053,300,000 fewer colors on Apple's display. Just saying.

Be it 16.7 million or 1.07 billion colors, we say, "Let's see what you've got, Crayola!"

It's important to note that Dell's "comparable" display is more expensive (when not on sale), does not connect via Thunderbolt, does not have built-in speakers, lacks a MagSafe connector for powering your MacBook, and is devoid of any data port other than USB. Dell's display is a really, really sweet 27" display. Apple's display is probably still the nicest panel you've ever seen, and is also a complete, single-cable docking solution for your MacBook.

Those are very valid points, Matthew. Apple makes it very clear who they are targeting with this device: people who purchased one of this year's Thunderbolt-enabled Macs. They have never pretended to be a peripherals company, and they do not try to capture any other part of the market. We just wanted to show how for a similar price point you can either go with Apple and get OEM integration and proprietary connectors, or you can choose Dell and get versatility.

I only wish they would use the first version first generation of the magsafe plug (straight white plastik housed)... with the thunderbolt cable going in perpendicular to the macbook edge and the magsafe L-shape cable pointing backwards it just looks awful...

1.07 billion colors are only possible with 10-bit color support: Apple doesn't support 10-bit color (yet) in their operating system(s) so far, and haven't made any comments suggesting that they plan to.

So, unfortunately, it would be a waste of one's money if they were to purchase a high-gamut display (like the Sharp 4K monitor that Apple currently offers with the Mac Pro) as the operating system will only render 8-bit color (16.7 million colors) on the display. It makes more sense for a Mac user to buy a cheaper monitor that supports 16.7 million colors, as those displays tend to be ⅓ of the price of those that support 1.07 billion colors.

Yes, it appears to be the same display found in the iMac Intel 27" from October of 2009, as well as the same basic LG display found in Dell's competing 27" monitor, though the Apple version uses LED backlights as opposed to Dell's traditional CCFL.

Dell's version is also matte, something that lots of Mac users have been harping for once the old 30" Cinema Display was phased out.

Stop—it's connector time! We remove a plethora (that's right, plethora, we're using our five dollar words) of connectors from the logic board, leaving only the brains behind the Thunderbolt port between us and the display's control center.

A few T6 Torx screws are knocked out to remove the connector cover, and the Thunderbolt cable is disconnected.

Interestingly enough, the Thunderbolt cable that routes into the display also plugs into a standard Thunderbolt socket on the logic board. Apple could have just soldered the cable wires to the board, but instead chose to implement a cover that prevents the cable from being detached from the logic board's Thunderbolt socket.

It's interesting to see the TB circuit board. Have you tried to find an Apple P/N for this board? In your opinion, is this what a vendor would need to simulate to build their own TB breakout box (along with a power supply)? Vendors keep saying it's going to be expensive to implement TB. From the looks of this circuit board, I might agree, however the range of I/O devices you get on this board is amazing.

Hot pot of coffee! Let's see what the Thunderbolt Display's power supply board can do for us.

How about 250 watts of maximum continuous power -- is that enough for you?

Fun science fact, the "thunderbolts" (AKA lightning) in nature can put out an average of 1,000,000,000,000 watts, that's 4 billion times the output of the Thunderbolt Display's power supply! But lets be fair...lightning bolts are much, much larger than this power supply and last only fractions of a second.

Apple now has a revised version of this power supply that looks slightly different, so newer Thunderbolt displays are not all alike. Not sure if the older power supply is any better or less prone to failure like the newer boards are.

Before you can do this step, you will need to remove the 4 screws holding the subwoofer on top and move it aside.

Would be nice if there were instructions on removing the thunderbolt cable. Beware that the grounded screw is the short one with the fine thread. Also note that the screws are going into plastic mounts which are easily stripped.

“While disassembly was very straightforward, there are a lot of parts, cables and connectors, making full reassembly not for the faint of heart.”

Especially using this teardown, which unlike most of the great guides here on iFixit, seems to favor levity over usefulness. It wouldn’t have been much more work to actually label things so it would be easier to know exactly what to do. Shame

Ass seen at the top of this page “This teardown is not a repair guide. To repair your Apple Thunderbolt Display, use our ++service manual++.” Teardowns are meant to be entertaining looks into a device, they are not intended to be step-by-step manuals.

OMG, through hole components on the power supply board! And hand smeared silicon glue! How could 20 years of technology gap exist in a leading Apple product? Bob, that Flextronics board needs to come off. I'm not buying until then.

Question re: "Interestingly enough, the Thunderbolt cable that routes into the display also plugs into a standard Thunderbolt socket on the logic board."

Would it then be possible to install a 3rd party Thunderbolt "external" HD inside the monitor by simply connecting it to the socket on the logic board, then daisy chaining another thunderbolt cable to the external port? Is there enough space?

I kinda think that Apple may allow Mac Minis run on MagSafe ports, and re-design the display's base to exactly fit a Mac Mini in (even include some screws and holes/nuts to allow users permanently connect their Mac Mini to the display). This combinition will definitely profit, and even can obsolote iMacs

Some more complicated redesign may include an optical drive into the display and can be accessed through Thunderbolt - makes the display combined with a Mac Mini totally an iMac.

You can't reasonably put a MagSafe port on a device that isn't battery-powered, and Apple has never put a system power battery into a desktop machine. Apple has never put external do-it-yourself mounting screwholes in a machine. Apple is in the process of removing optical drives from their hardware, not adding them. Except for the short-lived PowerBook Duo, Apple machines have always been designed to stand alone, not as an assembly.

If you want an iMac, just get an iMac. I'm impressed that you know enough about Apple's design, manufacturing, and market positioning to know what design changes will "definitely profit", even though it would "obsolete" their only consumer desktop line, but I don't see much consistency here with any other decisions Apple has made.

IFIXIT, I have a question!!! I'm the creative director of a video production company and I'm looking for a new monitor. I've always considered Apple displays to be too overpriced, but I was utterly shocked to be informed by a third tier Apple tech support guru that these displays had an IPU on their logic board to handle the load if your computers GPU get's bogged down. I've only found two other unconfirmed rumors of this.

When you tore down that display like Mel Gibson does to Jewish people and wives, did you by chance any such corroborating evidence?

I have the similar problem with the Thunderbolt 27 Inch Backlight. The Mac recognize the Display but have not picture. I see today the supply of the mosfet elements for the LED backlight have 25V but have not siglans from the HV9982.

I was looking to replace the glass apple logo with an led one. I have my thunderbolt display apart and as you can see in the last photo of this guide, there seems to be a silver foil over it. I do not want to tamper with it, but does anyone know if I will ruin anything if i take that foil off thats stuck to the metal frame? It appears that the apple logo is just glass, and that the foil on the inside is so sealed that it makes the apply logo look black. Any comments?

the thin 2 wires with the small board attached and adhered to the case a few inches to the left of the power cable hole. I have only found that on one monitor though they all have the port on the motherboard it is just empty on all the ones sans the thin wires and board adhered to the case. My question is... What is it and why is it not on all the displays??

The 1/4 inch square board adhered to the back of the case 4 inches to the left of power cable hole 1/2 inch to the right of 1 1/2 inch square black foam adhered to the case. Can be seen in image #20. The connected two thin wires are routed up and around hinge assembly. It connects to the second port down on the visible side of the motherboard. The port is on all motherboards but I have only found one display that has this small board, all other displays leave this port empty and do not have this configuration.

T Mac - I believe the item you speak of is a temperature sensor. On my display it is attached to the back side of the LCD panel itself and gets unplugged from the logic board during the panel removal (which is why the port appears to be empty in the other photos you've seen). At some point Apple must have switched from mounting it on the back of the case to mounting it on the back side of the LCD.

OK, mine died following the electrician switching the power off then on a couple of times. Given the there is no power on the external power connecter I'm assuming the power supply is gone. But are there embedded fuses in there that are likely to be the culprits?

I recently had a problem with my Thunderbolt Display turning black after short period of usage. Ranged from minutes to hours. The display was still recognized by the computer, it's just that the screen was black. After turning it in for repair a technician said it was the logic board, and changed it and charged me. It worked for a couple of days and then the same problem was back. This time the repair shop says it's the LCD display. My hunch is that it was the LCD all the time. My question, even though a bit vague: would my computer be able to recognize a display with faulty logic board? It feels like I'm being tricked by the repair shop.
